SUPPORTING-STRUT FOR SHOW-CARDS, PHOTOGRAPH-FRAMES, AND OTHER ARTICLES.

Specification of Letters Patent.

Patented Feb. 27,1917.

Application filed October 1'7, 1913. Serial No. 795,733.

To all whom it may concern:

Be it known that I, WILLIAM JOHN BROOKS, a subject of the United Kingdom of Great Britain and Ireland, residing at IVestholm, Letchworth, in the county of Hertfordshire, England, have invented a new and useful Supporting-Strut for Show- Ga-rds, Photograph-Frames, and other Articles, of which the following is a specification.

My invention relates to improvements in supporting struts for use with show cards, photograph frames, mirrors and other articles in which symmetrically hinged and pivoted members cooperate to provide a rigid and convenient supporting strut.

I attain these objects by the device illustrated in the accompanying drawings, in which Figure 1 shows the strut attached to the back of a show card, photograph frame or the like and lying fiat thereon; Fig. 2 a side View of the strut extended into its support ing position, and Fig. 3 a back view of the strut when so extended.

Similar figures refer to similar parts throughout the several views.

In Fig. 1 the strut is shown lying fiat against the back of show card 1. The strut is formed of a leatherboard blank or shape 2, which is hinged by creasing or otherwise, at 3 and 4: along lines which are inclined to their line of connection with each other, the hinges 3 being inclined to the hinge 4. central slot or notch 5 is cut in 2 and two holes are punched at 6. The strut is attached to the show card by two eyelets, rivets or the like 7 either directly to the show card, or, as shown in Fig. 1, to a piece of cardboard or the like 8, which in its turn is attached to the show card by gluing, riveting, eyeleting or other suitable means.

Figs. 2 and 3 show (respectively in side and back view) the strut extended into the supporting position, which position is attained by causing the members 9 to rotate symmetrically inward about the centers 7 thus by reason of the hinges 3 throwing outward the members 10 which fold together by reason of the hinge 1. The eyeleting or the like is so done that the parts 9 move with Copies of this patent may be obtained for moderate friction about 7 so that the strut retains the extended position. In Figs. 2 and 3 the strut is shown attached directly to the show card. In Fig. 3 the dotted lines show the fiat position from which the strut has been moved.

It is understood that in the above description the word show-card is used for the sake of brevity to indicate show card, photograph frame or other articles.

The strut may be made of any suitable material.

I claim:

1. In a supporting strut for show cards and the like, the combination with the article to be supported of two members each pivotally attached to the back of the said article so as to permit partial rotation in a plane parallel to that of the back of the said article and of two other members hingedly connected to each other and hingedly connected to the first named members.

2. In a supporting strut for show cards and the like, the combination with the article to be supported of two members; an eyelet pivotally attaching each of the said mem-' bers to the said article; and two other members hingedly connected to each other and to the first named members.

3. .In a supporting strut for show cards and the like, the combination with the article to be supported of two members each pivotally attached to a part of the said article, and of two other members hingedly connected to 'each other and hingedly connected to the first named members along lines which are inclined to their'line of connection with each other.

I. In a supporting strut for show cards and the like, the combination with the article to be supported of two members each pivotally attached thereto and of two other members hingedly connected to each other and to the first named members, all four mem-.

bers being fashioned from a single piece of leatherboard.
